Three cases of oesophago-pleural fistula are presented. Two resulted from foreign body perforation of the oesophagus and one followed left lower lobectomy for bronchiectasis. All three presented late; the time lapse ranged from 6 days to 2 months. An initial course of conservative treatment was given to all three patients. Alimentation via nasogastric tube feeding, gastrostomy or total parenteral nutrition was carried out. The pleural fluid grew the anaerobe, Bacteriodies melaninogenicus, in all three cases. Gram-negative aerobes, Escherichia coli and Proteus mirabilis, were also cultured. Closed intercostal drainage and a course of appropriate antibiotics were instituted. The patients were subjected to surgery after the infection had been brought under control. Simple repair was performed in two patients. Exclusion of the oesophageal leak with drainage and later reconstruction was carried out in the third patient. Although all three patients recovered, the morbidity was considerable. The duration of hospital stay ranged from 2 to 4 months.
